Although many cuttings come from Graduals, this example comes from an Antiphonary, as the verso contains part of the music for the Passion Sunday office.

Here, however, the initial illustrates the third lesson, from the Gospel of John (8:46–59). During a dispute in the temple the Jews accused Jesus of being a "Samaritan and having a devil," asking if he was greater than Abraham. When he responded that "before Abraham was made, I am," they were angered and tried to stone him, but Jesus hid himself and left the temple.
